Bjh. Meddens et al., STABILIZATION OF THE OUTPUT POWER OF A 20-MW KLYSTRON TO WITHIN 0.1-PERCENT, Review of scientific instruments, 64(8), 1993, pp. 2306-2311
For operation of a free electron laser, requirements on electron energ
y stability are extremely tight. When a radio frequency field is used
to accelerate the electrons, this leads to stringent requirements on t
he stability of the klystron output power. We present results obtained
with a 20-MW klystron which is energized by a pulse-forming network.
The achieved stability of the klystron power is better than 0.1% durin
g 20 mus.
